PIONEER’s independently-developed and produced PSA-CO adsorbent PU-1 was granted the Chinese, USA and Canadian patents. PU-1 has ultra-high adsorption capacity and selectivity for CO, which are the key features for PSA-CO technology which reaches the advanced level in the world.


PIONEER developed the process of the formation of a unique CO separation technology of blast furnace gas and converter gas. Based on the advanced pressure swing adsorption and separation of carbon monoxide process, PIONEER also successfully developed calcium carbide furnace exhaust purification and phosphorus off-gas purification technologies, and has taken a big step towards energy conservation and environmental protection.

PIONEER originates the high and low consumption PSA-CO technology based on PU-1 adsorbent, achieving the efficient separation of CO from nitrogen, methane and other components, which is of great importance for the carbonyl synthesis industry.
